摘要

The invasive Asian longhorned beetle, Anoplophora glabripennis (Motschulsky), is a destructive xylophagous forest pest species originating from Asia. Several endemic North American hymenopteran (Braconidae) species in the mid-Atlantic region were capable of attacking and reproducing on A. glabripennis larvae in laboratory bio-assays. Ontsira mellipes Ashmead (Hymenoptera: Braconidae) has been continually reared on A. glabripennis larvae at USDA-ARS BIIRU since 2010, and has been identified as a potential new-association biocontrol agent. Two experiments were conducted to investigate parasitism, paralysis, reproductive biology, larval development, and longevity of adult O. mellipes. In the first experiment, pairs of adult parasitoids were given single A. glabripennis larvae every 2 d (along with honey and water) over their lifetimes, while in the second experiment individual parasitoids were observed daily from egg to adult, and adults were subsequently starved. Adults in the first experiment parasitized similar to 21% of beetle larvae presented to them throughout their life, and paralysis of larvae occurred 1-2 d after oviposition. More than half of the individual pairs parasitized A. glabripennis larvae, with each female producing around 26 offspring throughout her life. In the second experiment, median development time of O. mellipes from egg to adult was about 3 wk, with five larval instars. Adult O. mellipes that were provided with host larvae, honey, and water lived 9 d longer than host-deprived and starved adults. These findings indicate that mass-rearing procedures for O. mellipes may be developed using the new association host for development of effective biocontrol programs against A. glabripennis.
